NAlL-DlSTRiBUTER FOR HEEL-NAILING MACHlNES.

SPECIFICATION forming part of Letters Patent No. 319,124, dated June 2, 1885.

Application filed January 17, 1855. (No model.)

To (LZZ 2071,0711 it may concern:

Be it known that I, Fnnnnonn F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvementin Nail'Feeding Machines, of which the following is a full, clear, and exact de scription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature.

The object of the invention is to provide a simple, easy, and efficient means of automatically supplying heel making and attaching ma' chines with nailsin amanner to permit of their being automatically distributed, delivered, and driven, and it is an improvement upon that described in my application for Letters Patent filed August 4, 1884,-Serial No. 139,595. In said application I have described as aportion of the invention a machine or device for making pointed nails from wire. I have also shown and described therein a distributing device for automatically receiving the nails from the nail-making mechanism and distributing them in a holder, and an automatic carrier for taking the nails from the holder and delivering them automatically into a position to be automatically driven by the drivers.

In thisinvention, instead of making the nails from wire, I make them from the nail-plate; and I use for the making of the nail any of the ordinary well-known appliances for so doingthat is, I employ any of the well-known nailplate-fecding devices and a reciprocating punchand I either use mechanism for vibrating the plate as employed in one class of heelnailmaking machines, or I oscillate or turn the punch in the manner common in another class of these machines; and as these parts of the device are common and well-known I have not illustrated them in the drawings, and shall not describe them further in the specification.

It is well known that heel-nails are made from nail-plate, heads and points. It is therefore apparent that the nails are formed alternately, one with a head pointingin one direction and the other with ahead pointing in the opposite direction; and the object of my invention is to provide means for receiving these nails as they fall from or are punched through the die, and for delivering them to the distributing device head up.

Referring to the drawings,Figurc l is a view, part in vertical section and part in elevation, of a machine containing the features of my invention. Fig. 2 is a side elevation thereof.

A represents the reciprocating punch which severs the nails from the end of the nailplate a.

. Bis the die through which the nails are punched from the nail-plate in succession by the punch. Arranged in the underpart of this die, so as to form an under surface thereto, and far enough from its surface to prevent the punch from coming in contact therewith when a nail is driven therein by the punch, but not so far as to permit the nail to turn as it falls, is acarrier or carrying device,0,which, while it may have but one surface for receiving and delivering the nails, preferably is pro vided with two, 0 and c. If it has but one surface, its operation is substantially as follows; It is held by mechanism, substantially as hereinafter specified, in a position to receive each nail as it is punched. After receiving such nail it is successively moved to the right, then to the" left, and always in a direction to move the point of the nail in advance of the head, so that if, for instance, anail has been out with the head to the right of the nail-plate, it falls upon the carrier, and the carrier then moves to the left, so that the nail is thrown or turned point downward. The next nail in order of course will have its head point to the left, and it will fall upon the carrier in that position, and the carrierwill then move to the right, so that it shall be brought into a vertical position with its point down. If, however, the carrier comprises one arm only, it will be necessary to provide it with quite a rapid movement in order that it may be in position to receive the hail from the punch and move to deliver it and return to its original position; and I have therefore found it advisable to provide the carrier with two surfaces, as represented in Fig. 1, so that each surface may be used alternately, one surface always feeding from the center in one direction and the other in the other, requiring simply a quarterturn of the shaft 0 to cause it to operate. These carrier-arms move between two parallel surfaces brought very nearly in contact therewith, and there is sufficient space between the upper surface of the carrier and the surface ICO to provide room for the passage of the nail, and there is arranged to extend downward from the delivering-point of each carrier a guide-tube, c", for the nail.

I prefer to use magnets or magnetized metal for the arms of the carrier, because they will hold the nail firmly to the carrier-surface, and the nail will not drop therefrom while the carrier is being turned from a vertical to a horizontal position. lVhen, however, I do employ magnets, it is necessary to use in addition a stripping device, and I have shown in the drawings the strippers D D, which are rods attached tothe cross-head A, carrying the punch and reciprocated thereby in holes (2, so arranged that their ends shall strip the nail from the ends of the carrier and move them well into the passages, in which they fall by gravity to the distributer E.

The carrier preferably is mounted on the shaft 0, and is moved at proper intervals by means of the gear-wheel c thereon. and the segment 0, which is pivoted at 0 and reciprocated by means of the cam-groove c in the cam 0 upon the shaft c WVhen magnets are not used for the carrier, it will be desirable to form the upper surface of the carrier inclined, as represented in Fig. 1, (see surface 0,) so that upon its revolution it shall not leave its surface until it has reached a position whence it can be delivered with certainty, point down, into the guide-tube c.

The distributer is like that described in my said application, with this exception, that there are two threats or tubes through which the nails are delivered to it instead of one, and

'in the drawings I have shown two throats.

These throats, however, may be so arranged that it shall require a complete revolution of the carrier to fili them-that is, if the movement of the carrier will be such that each throat will feed to alternate holes in the distributor; and I have shown the distributer as revolved by substantially the same mechanism as that described in the same applicationnamely,a ratchet-pawl operated by a lever, and a cam, the cam in this instance being preferably the same cam that operates the segment.

The nails to bedelivered to the distributer are by it delivered to the nail-holder, and from the nail-holder fed to the heels or drivers, as described in my said application.

The advantages of this inventionarise from the use of a carrier which receives the nails as they are punched, and delivers them to the distributer with their points down.

Having thus fully described my invention, I claim and desire to secure byLetters Patent of the United States-- 1. The combination,with nail-punching devices arranged to cut nails heads and points from a nail-plate, of a carrierhaving the movements in relation to the die set forth, whereby the nails are received in succession from the die and. delivered head up in their respective passages, all substantially as and for the purposes described.

2. The combination of the reciprocating punch A, the die B, and a carrier comprising one or more magnets adapted to receive and hold each nail, and to move it in a direction to bring its head uppermost, and a stripping device, all substantially as and for the purposes described.

3. The combination ofv the punch A, the die B, the magnet-carrier, the guide-tubes c, and the strippers d, all substantially asand for the purposes described.

4. The combination of the die B, the carrier O, and a cam for moving the same, all substantially as and for the purposes described.

5. The combination of the punch and die, the carrier 0, adapted to receive and deliver the nails, as specified, the guide-tubes c, and the distributer, all substantially as and for the purposes described;

6. The combination'of devices for punching nails from nail-plate and delivering them head up to a distributer, the distributer, and acarrier for transferring the nails fromihe distributor to a driving position, all substantially as and for the purposes described.

7. The combination of devices for punching nails from a nail-plate and delivering them heads up to a distributer, said distribnter, and a nailzholder, all substantially as and for the purposes described.
